Former adult star Jennifer Ketcham (aka Penny Flame) at one time entered “Sex Rehab with Dr. Drew” because she thought it would boost her career in porn.

But as she quickly found out, it wasn’t going to be quite that easy.

Ketcham had a number of issues going into rehab – troubles with family, addictions, relationships and more. She lost her virginity at age 13 and began a game of “initiating” boys her age into manhood.

Dr. Drew and his staff insisted they call her by her real name. She eventually began to acknowledge her shortcomings and started to change her ways.

She has since written a book entitled “I Am Jennie.”

Ketcham told Dr. Drew Monday night, “[People are going to] read about a woman who thought that her life was over at 26 and who happened to meet some very wonderful people that helped her change everything in her life.”

She added, ‘[If I had to do it over again], I would not change a single thing. Every single thing that has happened in my life has brought me to this moment … my biggest hope in publishing the book is that it can help at least one other person..”

Ketcham says she now works as a restaurant hostess, and goes to school full-time where she’s pursuing a bachelor's degree in psychology
